Specification of Letters Patent.

Patented April 17, 1906,

Application filed August 3, 1905. Serial No. 272,514.

To all whom it may concern:

Be it known that I, WILLIAM MURRELL TAY- LOR, a citizen of the United States, and a resident of Mecklenburg, in the county of Meeklenburg and State of Virginia,have made certain new and useful Improvements in Auxiliary Rud ders, of which the following is a specification.

My invention is an improvement in auxiliary rudders; and it consists in certain novel constructions and combinations of parts hereinafter described and claimed.

Referring to the drawings forming a part hereof, Figure 1 is a side view of a part of a vessel supplied with my improvement. Fig. 2 is a section on the line 2 2 of Fig. 1. Fig. 3 is a detail perspective view of a frame and vane without the braces.

In the present embodiment of my invention, A designates the hull of ,a ship, having on either side, adjacent to the stern thereof, the rectangular recess a. The four corners of the recess are provided with perforations extending through the hull, and within the hull adjacent to the perforations are a plurality of rollers (1 the rollers being arranged. two upon each side of the vessel within the compartments formed between the watertight partitions a and the hull.

A frame B, comprising the longitudinal bars I) and the end bar 5, is hinged within the recess to the rear sides thereof, and the free ends of the side bars on each side of the vessel are connected to the respective members of the front pair of rollers by means of the chains 17 or any other suitable flexible connection.

Varies or fins C are hinged within the frame, to the front edge thereof, the free ends of the fins on each side being connected to the respective. members of the rear pair of rollers by means of the chain c. The upper and lower edges of the fins are cut away, as at 0 forming recesses for the reception of the braces D, pivoted to the sides of the fins within the recesses and having longitudinal slots cl engaged by pins 6 on the longitudinal bars of the frame, the free ends of the braces being beveled, as at (i for engaging the side of the hull.

In operation when the chains on the front rollers are loosened to allow the front end of the frame to spring outwardly the fin or vane swings outwardly therewith. This action is due to the force of the water acting in a di tightened to hold the free end of the frame inward, the front or attached end of the fin moves therewith, thus bringing the beveled end of the brace into contact with the hull and holding the fin in such position that the rear or free end is farther from the hull than the front or attached end. As a consequence of this position the direction of force of the water is oblique to. the outer face of the fin and tends to move'the entire device inwardly. The braces maintain the parts in the above described position until the device is almost in the recess or until the closing movement brings the parts into parallelism with the iongitudinal bars of the frame. The beveled free end of the brace slips along the hull as the fin is pulled inwardly.

While I have described my improved rudder as provided with the braces, it is evident that it could be used without the same, the action of the said braces being only to make the vane and frame self-closing.

In order to insure the proper opening of the device, I provide the shaft E, journaled on the inside of the hull adjacent to the frame, within the compartment, the said shaft being provided with cams e for engaging the upper and lower longitudinal bars of the frames, respectively.

Any suitable means may be provided for rotating the shaft to bring the cams into action to force the frame slightly outward from the sides of the vessel into a position where the water will engage the same.

Any suitable means may be provided for actuating the rollers; but since such means forms no part of my invention I have not deemed it necessary to describe the same.

It will be evident from the description that my improved auxiliary rudder, while simple in-construction, is yet efficient in operation, and when the desired end is attained it is very quickly drawn out of action, which is a most important feature in devices of this class. Owing to its peculiar construction, the

action of the flowing water helps to close it, as Well as to open it, thereby requiring very little power to manipulate the same.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The combination with the hull of a ship having recesses adjacent to the stern, of rectangular frames hinged within the recesses to the rear end thereof, a fin hinged within the frame to the front end thereof, longitudinallyslotted braces pivoted to the fin and projecting rearwardly along the sides thereof, pins on the frame for engaging the slots, a plurality of pairs of rollers journaled within the hull, and flexible connections between the free ends of the fins, the free ends of the frame and the respective pairs of rollers.

2. The combination with the hull of a ship having recesses adjacent to the stern, of rectangular frames hinged Within the recesses to the rear end thereof, fins hinged Within the frame to the front ends thereof, a plurality of pairs of rollers ournaled Within the hull and flexible connections between the free ends of the fins, the free ends of the frame, and the respective pairs of rollers.

3. The combination with the hull of a ship having'recesses adjacent to the stern, of rectangular frames hinged within the recesses to the rear end thereof, fins hinged within the frames to the front ends thereof, and means for opening and closing the fins and the frames.

4. The combination with the hull of aship of frames hinged at their rear ends to the stern thereof, fins hinged within the frames at the front ends thereof, and means for opening and closing the frames and the fins.

5. The combination with the hull of a ship, of a frame hinged by its rear end to the stern thereof, a fin hinged within the frame at the front end thereof, longitudinally slotted braces pivoted to the fin and projecting rearwardly along the sides thereof and pins on the frame for engaging the slots of the braces.

6. The combination with the hull of a ship, of frames hinged at their rear end to the sides of the hull adjacent to the stern thereof, fins hinged within the frame at the front ends thereof and means attached to the fin for engaging the hull whereby to maintain the fin in a position such, that the force of the water acts upon the outer face thereof.
